Tunable TiO₂–BN–Pd nanofibers by combining electrospinning and atomic layer deposition to enhance photodegradation of acetaminophen

Abstract

The demand for fresh and clean water sources increases globally, and there is a need to develop novel routes to eliminate micropollutants and other harmful species from water. Photocatalysis is...

Design of halloysite-based nanocomposites by electrospinning for water treatment

“…1.c). This also confirmed that the moderate amount of TiO2 was uniformly distributed in the H95T5 hybrids, as previously reported 39,40,[53][54][55][56][57][58][59][60][61] . To study the sample crystallinity, XRD analysis were carried out.…”

“…The R2 value of H95T5 (5% of TiO2) increased to 1280 Ω. The R2 of HNT was 6027.8 Ω, which indicates lower recombination rate between electrons and holes and thus, longer electron lifetime 57 .…”

“…TiO2 nanofibers (Fig. 3.b and e) showed a rough and large surface 57,61 . The surfaces of H95T5 nanofibers and TiO2 nanofibers were similar (compare Fig.…”

“…This demonstrated the participation of O2 •− in the photodegradation process. Addition of EDTA led to degradation inhibition by ~70%, indicating that h+ also were involved in ACT degradation 57 . Overall, these data showed that • OH, h + and O2 •− radicals were the main reactive species involved in ACT photodegradation 57 .…”

“…Addition of EDTA led to degradation inhibition by ~70%, indicating that h+ also were involved in ACT degradation 57 . Overall, these data showed that • OH, h + and O2 •− radicals were the main reactive species involved in ACT photodegradation 57 . Lastly, bacterial toxicity tests were performed to determine whether toxic by-products were produced during ACT degradation.…”
